1 c.yahoo.com. . (c,b,g,m,d,h,e,a,f,i,j,k,l).root-servers.net. 2 c.yahoo.com. com. (j,k,h,c,g,m,a,d,f,l,i,b,e).gtld-servers.net. 3 c.yahoo.com. yahoo.com. (ns1,ns2,ns5,ns3,ns4).yahoo.com.
We pick c.root-servers.net , one of the 13 root servers (1), and ask it about c.yahoo.com and learn that com is delegated to 13 name servers (2), so we ask j.gtld-servers.net where we learn that yahoo.com is delegated to five name servers, including ns1.yahoo.com (3), so we ask that one and get the following answer:
Authoritative answer
